ASoC: SOF: ipc3-control: Fix TOCTOU in bytes_put and bytes_get<\/p>\n
In sof_ipc3_bytes_put(), the size used for the memcpy is derived from
\nthe old data->size already in the buffer, not the incoming new data’s
\nsize field. If the new data has a different size, the copy length is
\nwrong: it may truncate valid data or copy stale bytes.<\/p>\n
Similarly, sof_ipc3_bytes_get() checks data->size against max_size
\nwithout accounting for the sizeof(struct sof_ipc_ctrl_data) offset
\nof the flex array within the allocation.<\/p>\n
Fix bytes_put to validate and use the incoming data’s sof_abi_hdr.size
\nfrom ucontrol before copying. Fix bytes_get to subtract sizeof(*cdata)
\nfrom the bounds check to match the actual available space.<\/p>\n","protected":false},"excerpt":{"rendered":"
